ROBERT D. SCOTT AND JOHN G. CADWELL, OF ROSLYN, WASHINGTON.

RUNNING GEAR FOR MINING CARS.

Application filed November 19, 1921.

To all to ho'm it may concern Be it known that we, ROBERT D. Soorr and JOHN G. CADWELL, citizens of the United States, and residents of Roslyn, in the county of Kittitas and State of Washington, have invented certain new and useful Improvements in Running Gears for Mining Cars, of which the following is a specification.

This invention relates to mining cars and more particularly to the running gear therefor.

The object of the invention is to provide an improved oiling arrangement, whereby it will be insured that the journal axle of the running gear will be continuously and thoroughly lubricated.

It is also an object of the invention to provide improved journal boxes for the axles and furthermore to provide an improved construction of axle.

Other advantages will hereinafter appear in the detailed description to follow.

The invention is illustrated by way of example in the accompanying drawings in which,

Figure 1 is a vertical transverse sectional View taken through a pair of companion wheels of the running gear of a mining car in which the present invention is embodied.

Figure 2 is a detailed vertical sectional view taken through one of the journal boxes of the same.

Figure 8 is a horizontal sectional view ltgaken through the cover or cap of a ournal Referring to the drawings more particularly B indicates the body of the car, J apair of journal boxes which are adapted for journalling the axle A and each journal box being provided with a cover or cap C. Jpon one end of the axle A there is journaled a wheel W and upon its other end there is fixed a wheel V and at R is indicated a rail for each of the wheels lV and lV.

More particularly each journal box J consists in the solid block casting comprising a base portion 10 which has formed therewith a reduced portion 11, said reduced portion having formed transversely of its lower base a suitable semicircular recess adapted for receiving the axle A. Also between the bearing casting and axle there is interposed a babbitt 12 to properly journal the axle. The cover or cap C in each instance com prises a body portion 13 and the skirt por- Speclfication of Letters Patent.

tion 14:, said cap as a whole being adapted to be fitted upon a journal box J and held in position by means of screws extending through the shirts 1% thereof and into the journal box (not shown). hen in this position the body portion 13 of the cap forms a container or chamber beneath the associated portion of the axle A in which waste 15 is placed. The waste 15 is adapted for retaining a suitable lubricating agent for the axle A and between the waste and axle there is interposed a fine mesh screen 16, said screening being suitably secured to the cover C and adapted for preventing the waste engaging with the axle from gathering sediment and grease and hardening thereon. This screen is of particular advantage in that it prevents the waste 15 from clogging so that it may at all times perform its function of lubricating the axle A.

Each end portion of the axle A is provided with a bore 17 extending longitudh nally thereof, as shown, and said bore 17 in each instance terminating in a reduced bore 18 which in turn communicates with the pair of transverse passages 19, said passages extending through the axle as shown. With: in the bore 17 in each instance there is positioned a casing .20, said casing beingin the shape of a capsule and having each end provided with an orifice 21. Within the casing 20 there is positioned compression spring 22 and a ball 23, said compression spring being adapted to urge the ball forwardly for closing the outer orifice 21 in the easing 20.

As before stated, the wheel is loosely mounted upon the axle A and the end or" the axle associated with this wheel is formed with a retaining collar 25 and between said retaining collar and the. hub of thewheel TY there is interposed a washer 26. Also the axle is formed with the transverse passages 27 which communicate with the bore 17 and by which the wheel W may be properly lubricated for oil. The other wheel TV is sweat ed upon the ends of the axle A or it may be secured by a key or the lik if so desired.

It is thought from the foregoing description that the advantages arising from the particular construction of the ournal boxes J may be apparent. lVith respect to the oiling arrangement shown it is quite clear that the axle A will be continuously and thoroughly lubricated by the waste 15 by extending the spoutof a can into th casing llO 20 and then injecting the oil into the bore 17 and from thence the oil will proceed through the bore 18 and passages 19 into the waste 15. The passages 19 may beef any number desired although two have been found to Also the wheel W may be lubricated by oil passing through the passagas 27.

ith respect to the construction of the axle A,the collar 25 makes positive assurance that the wheel W cannot leave the axle. Also as before stated the wheel W is'loose upon the axle while the wheel W is fixed. This construction is for the purpose of permitting the loose'wheel to compensate for increased length of outer rail when the car track should make a curve and loosens the tractive effort for drawing the car and also the wear upon the wheels and rail.

' What we claim is:

l. A journal box construction for car axles comprising a solid casting having a transverse recess in its lower base adapted for j ournalling an axle, a cap adaptedto fit upon the casting and cover the lower side of the axle andalso adapted to form a compartment beneath said axle in which an oil retaining agent may be placed.

2. A journal box construction for car axles comprising a solid casting having a transverse recess in its lower base adapted for journalling an axle, a cap adapted to fit upon the casting and cover the lower side of the axle and also adapted to form a coinpartment beneath said'axle in which an oil retaining agent may be placed, and a reticulated sheeting carried by said cap and inter-- posed between the oil retaining agent and the axle for the purpose described.

3. An axle journal construction for carsof the character described comprising a casting conslsting in a base portion formed with a downward-1y projecting journal portion,

said journal portion having formed trans-- versely thereof a semi-circular recess adapted for receiving an axle, a cap fitting upon the lower side ot'the journal casting, said cap also forming a chamber beneath the axle in which waste may be positioned, and passages extending through the axle and communicating with the chamber of said cap 'whereby oil may be supplied to said waste.

4. An axle journal construction for cars or the character described comprising a castingconsisting in a base portion formed with a downwardly projecting journal portion, said ournal portion having a semi-circular recess adapted for receiving an axle, a cap adapted for fitting upon the lower side of the ournal castlng, said cap being also in which waste may be positioned, and said compartment formed by said cover adapted V to communicate with a passage extending longitudinally of the associated axle from one end thereof whereby oil may be supplied to said waste, and means within the passage 01 said axle 'adapted to normally close the same against the entrance of'dust or other foreign matter. 7
